Psalms 37:5

7. “For mine iniquities have lifted up my head; and are like a heavy burden too heavy for me to bear” ( ver. 4 ). Here too he has placed the cause first, and the effect afterwards. What consequence followed, and from what cause, he has told us. “Mine iniquities have lift up mine head.” For no one is proud but the unrighteous man, whose head is lifted up. He is “lifted up,” whose “head is lifted up on high” against God. You heard when the lesson of the Book of Ecclesiasticus was read: “The beginning of pride is when a man departeth from God.” He who was the first to refuse to listen to the Commandment, “his head iniquity lifted up” against God. And because his iniquities have lifted up his head, what hath God done unto him? They are “like a heavy burden, too heavy for me to bear”! It is the part of levity to lift up the head, just as if he who lifts up his head had nothing to carry. …

4. “For the enemy hath persecuted my soul: he hath humbled my life on the earth” ( ver. 3 ). Here we speak, here our Head speaketh for us. Manifestly both the devil persecuted the Soul of Christ and Judas the Soul of his Master: and now too the same devil remaineth to persecute the Body of Christ, and one Judas succeedeth another. There lacketh not then of whom the Body too may say, “For the enemy hath persecuted my soul.” For what doth each one who persecuteth us endeavour save to make us abandon our heavenly hope, and savour of the earth, yield to our persecutor, and love earthly things? “They have laid me in dark places, as the dead of the world.” This ye hear more readily from the Head; this ye perceive more readily in the Head. …

But if even after all this, virtue seem to thee an irksome thing, consider that vice is more irksome. And this very thing He was intimating, in that He said not first, “Take my yoke upon you,” but before that, “Come, ye that labor and are heavy laden;” implying that sin too hath labor, and a burden that is heavy and hard to bear. For He said not only, “Ye that labor,” but also, “that are heavy laden.” This the prophet too was speaking of, when in that description of her nature, “As an heavy burden they weighed heavy upon me.” And Zacharias too, describing her, saith she is “A talent of lead.”

Wherefore we must cast out all wickedness from our souls, and never more contrive any deceit; for, saith one, “To the perverse God sendeth crooked paths” ( Prov. xxi. 8 , LXX.); and, “The holy spirit of discipline will flee deceit, and remove from thoughts that are without understanding.” ( Wisd. i. 5 .) For nothing maketh men so foolish as wickedness; since when a man is treacherous, unfair, ungrateful, (these are different forms of wickedness) when without having been wronged he grieves another, when he weaves deceits, how shall he not exhibit an example of excessive folly? Again, nothing maketh men so wise as virtue; it rendereth them thankful and fair-minded, merciful, mild, gentle, and candid; it is wont to be the mother of all other blessings. …
